IMPROVZEDPROCESS 0F VAPORIZING AND DECOMPOSING HYDROCARBON LIQUIDS IN THPRESENCE 0F STEAM.

Specification forming part of Letters Patent No. 68.708, dated September 10, 1867.1

VTo all whom it may concern .r l

\ Be it known that we, FREDERIC COOK, of

V the city, county, and State of New York, and -JOHN A. BAssE'rT, of Salem, in the county of Essex and State of Massachusetts, have invented a new and useful Process for Vaporiz.

ing and Decomposing Hydrocarbons in the Presence of Steam 5 and we do hereby declare the following to be a full description ofI the same, referring to theannexed drawings- Figure l of which is a horizontal section through line A B,` Fig. 2. Fig.2 is a vertical vsection through C D, Fig. 1.

Similar letters of reference indicate like parts in both figures. v

The nature of our invention consists in decomposing the. vapors of hydrocarbon oils,

and combining therewith the products of the decomposition of steam, the steam being decomposed upon red-hot carbon, and the vapors `of the oil being .eliminated simultaneously with the decomposition of the steam. Both are 'passed through the red-hotv carbon, and the resultant gases may be used for the production of heat and light.

In the arrangement'shown and described this process is applied to a furnace for the production of heat, the decomposed gases being used as fuel.

In all the methods heletofore showinfor.

burning oils as fuel, in which steam is used,

no provision has been made for the thorough decomposition of the steam. A

In the burning of la substance containing so large a proportion of easily-eliminated can bon it is desirable to provide it with a properquantity of non -luniiniferous gases, such as lcarbonio oxide and hydrogen, both of which vare obtained by decomposing the steam upon red-hot carbon, and readily mix with and dilute the rich gases from petroleum and other oils, so that thorough combustion, without smoke, mayensue, and the equivalent ofthe heating value of the oil obtained as near as possible.

The oil to be decomposed is supplied, underl pressure, in any suitable manner, through the oil-pipe E. It enters, as shown, the lower portion of 'the retort F and strikes against the heated tile-surface Gr, where it is partially vapored and ignited. A

Vbottom ofthe chamber.

rIhe steam is admitted through pipes H oneach 'side of the retort.` I is .an-airbox all round the retort, into which air is forcedV `through the pipeJ. The forced air-passes" through Ithe perforations K into the'lower` chamber of th'e retort.

l'Ihe mixture of burned and unburned gases, steam, and air is made to passthrough the through the holes N.

O is a hollow perforated cone of `tire-clay,

suspended from the top of the furnace, -which, becoming highly heated, aids `in the `perfect coulbustionof the gases.

The retorts L are so arranged as to drop to the bottom by means of the catches P, which, when turned opposite the slots Q,`fall to the of the retort, arranged on hinges to drop down,

and fastens by thepin and 'key S.

The coke will require renewing from" time to time as it is decomposed by the steam'.

The size of the retorts shouldbe made to correspond proportionatelywith" the ysize of ,y

the furnace, and 'we prefer to make them u in the form shown, whereby the height is greater than the area, for the purpose of causing the.

steam to pass through a long vertical section of highly-heated, carbon, and, by lwhih the steam lis fully decomposed.- i

Having thus' fully described thenature `of; our invention., what we claim as new, and desire to secure by Letters Patent, isn 1. In an apparatus for decomposing hydrocarbon oils with steam,we claim the arrangement and construction of the apparatus shown, u having the several .parts or their equi\ ralents Y arranged and operating together in the manner and for :the purpose specified.

` 2. The process hereinv described 'whereby hydrocarbonoils and steam are decomposed into gases, and usedvin v the simultaneously ,productionof heat, as set forth.: i
